Answer: its The ability to do work or cause change. Energy of an object due to its motion.
Explanation:In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.
Answer:
velocity shsjshsuud7dudhdudbe
The object takes 8 s to reach a velocity of 48 m/s south
Explanation:
Since the motion of the object is a uniformly accelerated motion, we can use the following suvat equation:
v = u + at
where
v is the velocity at time t
u is the initial velocity
a is the acceleration
t is the time
For the object in this problem, choosing south as positive direction, we have:
u = 16 m/s
v = 48 m/s
So we can solve the equation for t to find the time taken for the velocity to change from 16 m/s to 48 m/s:

It means that 19.3g of gold is packed into 1cm^3.
Answer:
Acceleration, a = 0.5m/s²
Explanation:
Given the following data;
Force, f = 20N
Mass = 40kg
To find the acceleration;
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
Where;
F represents force.
m represents the mass of an object.
a represents acceleration.
Making acceleration (a) the subject, we have;
Substituting into the equation;
Acceleration, a = 0.5m/s²
Therefore, the acceleration of the bookcase is 0.5m/s²
